However, the documents state that Corsi later replied to Stone, “Word is friend in embassy plans 2 more dumps. One shortly after I’m back. 2nd in Oct. Impact planned to be very damaging," appearing to refer to WikiLeaks founder Julian Assange.

Mueller has been eyeing both Stone and Corsi in relation to WikiLeaks's release of damaging Democratic emails in the weeks leading up to the 2016 presidential election as part of the investigation into Russia's election interference and possible collusion between Trump's campaign and Moscow.

Stone, a former Trump campaign adviser, and Corsi have both denied being in contact with Assange.

Corsi has also said that he "deduced" that the emails from Clinton campaign chairman John Podesta would be released because they weren't included in a previous dump of Democratic emails.

Stone, meanwhile, has said that he had a source who told him that WikiLeaks had damaging information that would disrupt the election.
